Rover 75 Symphony audio system
Hi Guys thought I would pass on this little tip (should work with any 75 and any audio system) - when disconnecting the battery it's normal to lose the radio security code, all well and good if you know what it is, but a real pro0blem if you don't!
Answer is to turn on headlights before disconnecting the battery, when you refit presto, all will be back to normal with no need to reset radio.
I know this works because changed battery at my local garage only yesterday, to day the original supplying dealer rang me back as promised having checked their PC system for my code, unfortuneately they could not give me this as not shown on system.
Does anybody know how to retrieve it from the ECU please, or can a MG Rover mechanic tell us what is maximum time battery can be taken off for without the need to rest?
